I have Dry setups saved to the game on all the tracks. Also for most of the tracks i have a wet setup. On some tracks i have saved career setups too. I got most of my setups from Race department but changed them to my preferences.

Pay no attention to the actual setup info as its waaay out of date as im in work and dont have the latest copy, but I got something like this going on for each track, and simply update as I evolve my setups...

I keep all the setups I found from here in formatted .txt files and uploaded them to a dropbox account so I can sync them to my ipod and have it on the go. I play the game at a few different pcs so it's easier for me to keep them with me.
